    Hello I was wondering if some one could help me with a fm jammer. I will be using it solely for myself so no need to worry. I seen this digram but I'm not good with themhttps://www.google.com/search?q=fm+jammer+circuit&safe=off&tbm=isch&tbo=u&source=univ&sa=X&ei=CtHfVOnYA4m5ggTVnoLYAw&ved=0CCoQ7Ak&biw=360&bih=559#imgrc=qpqM1H0n1IOO6M%253A%3BF9cCHRpzbfBjSM%3Bhttp%253A%252F%252Fwww.next.gr%252Fuploads%252F135-ff742f5154.gif%3Bhttp%253A%252F%252Fwww.next.gr%252Frf%252FJammer-Circuits%252F%3B555%3B306

    Also I seen a video on YouTube where they guys uses a fm transmitter chiphttp://youtu.be/TDcDWqCqWqI

    I have these two chips but was wondering if they would workhttp://html.alldatasheet.com/html-pdf/46653/SONY/CXA1691BM/611/7/CXA1691BM.html

    Don't know of its illegal in the US, but the fm jammer works on one frequency at a time, basically its a transmitter at a certain power,which will obviously need a license for.

    You want to jam your own FM reception?? :confused: Jamming anyone else's would be illegal.

    Sounds illegal to me, why do you want to jam a radio station, just dont listen to it, retune...

    Why do you want to jam yourself?

    Actually, I can think of several reasons -- in fact some work I did a few years back needed the ability to generate jamming signals to evaluate the jam-resistance of what we were working on, so it's not at all inconceivable that you have a very benign intent.

    But, in general, jammers and other similar things are not well-received by the owners and mods here. Phone jammers are specifically prohibited by the ToS.

    Then what you want is a narrow-band rejection filter, not a jammer (which is a transmitter, as Dodgydave stated). Do you have a schematic for the RF front end of your FM receiver?

    That depends on where you are. And how do you intend to keep the effect constrained to your house? And why do you want to jam a certain radio station as opposed to just not tuning it in? Are your kids listening to something you object to? If so, you are treating the symptom and not the problem.

    This thread is against the AAC forum rules, Chapter 6, as seen here:

    This includes any kind of RF jammer.

    This can be found in our Terms of Service (ToS)

    Here is a site that may provide you with some assistance: Electro Tech Online

    Good luck
